微生物菌肥与化学肥料配施对盈江省藤生长的影响

为了解不同肥料种类及其施肥量对盈江省藤生长的影响，采用L₉(3⁴)正交试验设计对其2年生幼林进行连续3年的微生物菌肥与复合肥和磷肥配施试验。结果表明，3年中不同因素的各水平组合间苗木的地径、株高、叶片数和冠幅均呈现极显著的差异(P<0.01)。施用复合肥和磷肥总体呈现显著(P<0.05)或极显著(P<0.01)地抑制盈江省藤生长的现象。不同肥料配施试验组合的地径、株高和叶片数均大于对照的相应指标。试验期间，单施微生物菌肥0.3~0.6 g/株即可满足盈江省藤生长的需求。

Effects of Combined Application of Microbial Fertilizer and Chemical Fertilizer on the Growth of Calamus nambariensis var. yingjiangensis

In order to understand the effect of different fertilizers and their fertilization scheme on the growth of Calamus nambariensis var. yingjiangensis, L₉(3⁴) orthogonal test design is used to carry out combined fertilizer application test of microbial fertilizer, compound fertilizer and phosphorus fertilizer on the living 2 a young forest for 3 consecutive years. The results show that:1) There are significant differences in the ground diameter, plant height, number of leaves and crowns of seedlings in different-level combinations of different factors (P<0.01); 2) The application of compound fertilizer and phosphorus fertilizer inhibits the growth of C. nambariensis var. yingjiangensis significantly (P <0.05) or very significantly (P <0.01); 3) The ground diameter, plant height and leaf number of seedlings in different fertilizer combinations are larger than those of the control; and 4) During the experiment, the application of microbial fertilizer alone with the amount of 0.3-0.6 g/plant can meet the growth needs of C. nambariensis var. yingjiangensis.
